Apologies in advance if I am posting this in the incorrect area (scanned through the categories and couldn't work out where would be the best place to post it) but anyone have any experience with Metaname ? I've moved my blogging provider to someone else and I'm looking at a NZ domain reseller and Metaname seemed to tick all the boxes.

They've been around since around 2009 and I've had domains with them for about that long too. Excellent provider! Also, you're supporting a local Christchurch based small business by having your domains with them :)

I used to be a Metaname customer but transferred all our names to VentraIP, and then Synergy (The wholesale section of VentraIP).

VentraIP/Synergy are the only company with DNSSEC support who I have confidence in and would recommend.

Angelo (the owner of Ventra/Synergy) is a regular on Whirlpool (Australian equivalent to Geekzone) and seems to be well liked. Most importantly, I have found he personally takes accountability for issues, when they have happened.

I note you said you wanted a NZ registrar, but if you considered Ventra/Synergy, I don't think you will find a better registrar.

I don't know how domain companies exist, and also provide good support, as there is very little money in it and tiny margins when selling domains so cheaply. Guessing it is all about upselling other services on top.

VentraIP/Synergy are the only company with DNSSEC support who I have confidence in and would recommend.

Metaname is really good. When Cloudflare started supporting DNSSEC I tried using Metaname but they did not support the specific algorithm required by Cloudflare DNS. I asked their support and less than 30 minutes later they replied with a "try now" and it just worked. I have confidence they're as good as the one you suggest.
